Abstract
Description
Technical Field
[0001] The invention belongs to the field of manure and sewage treatment equipment, and in particular relates to a side-push type sewage fermentation treatment system and a sewage treatment method. Background Art
[0002] The manure treatment equipment in the prior art generally adopts the method of simply raking and pushing the waste to be treated on the material plate. For example, the utility model patent with the authorization announcement number CN 210261529 U discloses a manure vertical evaporator, which is provided with a multi-layer evaporation conveyor belt device, and the manure is spread on the evaporation conveyor belt device and moves with the evaporation conveyor belt device to dry the manure; a raking device is provided on each layer of the evaporation conveyor belt device, which can rake and crush the manure on the evaporation conveyor belt device. However, the manure vertical evaporator in the prior art has the following defects:
[0003] After being transported from one end to the other end on the evaporation conveyor device, the material falls directly, and is raked by the raking device above before falling. On the one hand, the waste is directly transported through the evaporation conveyor device, and the residence time on each layer of the evaporation conveyor device is short, making it difficult to achieve effective fermentation; on the other hand, even if the residence time of the material on the evaporation conveyor device can be controlled as much as possible by controlling the transport speed of the evaporation conveyor device, since the material only undergoes a simple raking when passing under the raking device, it is difficult to achieve a good raking and crushing effect on the material. If attempts are made to arrange more raking devices along the length direction of each layer of the evaporation conveyor device, this will undoubtedly increase the complexity of the mechanism and greatly increase the production cost and maintenance cost; furthermore, in order to fully increase the residence time of the pollution on each layer of the evaporation conveyor device, the length of the evaporation conveyor belt is usually designed to be longer, making the mechanism too large and difficult to use in small waste fermentation treatment spaces. Summary of the invention
[0004] Technical issues to be solved
[0005] Based on this, the present invention proposes a side-push type sewage fermentation treatment system and sewage treatment method, which aims to solve the technical problems of poor fermentation effect and low efficiency of multi-layer fermentation equipment for sewage in the prior art.
[0006] Technical Solution
[0007] In order to solve the above technical problems, the present invention proposes a side-push type sewage fermentation treatment system, wherein the side-push type sewage fermentation treatment system comprises:
[0008] A fermentation rack, the fermentation rack comprising a material support table;
[0009] A raking device is arranged to move relative to the material support platform, and the raking device can at least move relative to the material support platform above the material support platform along a first relative movement direction. The raking device includes an angle raking element, and the angle raking element is arranged at an angle to the first relative movement direction at least in a raking working state, so that when the raking device moves relative to the material support platform above the material support platform along the first relative movement direction, the material on the material support platform can be pushed by the angle raking element in a direction forming an angle with the first relative movement direction.
[0010] Furthermore, the angle raking element is arranged at an angle of 10° to 60° with the first relative movement direction at least in the raking working state.

[0012] Furthermore, a material drop hole is provided on the edge in the width direction of the material support table, and when the raking device moves above the material support table along the length direction of the material support table, the angle raking element pushes the material on the material support table along a direction forming an angle with the first relative movement direction and toward the material drop hole.
[0013] Furthermore, the material blanking through hole is at an edge of the material support platform in the width direction and extends from one end of the material support platform to the other end along the length direction of the material support platform.
[0014] Furthermore, the fermentation rack includes a base frame, the material support platform has multiple layers, the multiple layers of material support platforms are arranged on the base frame from top to bottom, and the material drop holes of the two adjacent layers of material support platforms are arranged on different sides of the width direction of the material support platform.

[0016] Furthermore, the number of the fermentation racks is 2, the traction device includes a turning roller, a hoisting mechanism and a traction rope arranged on the hoisting mechanism and the turning roller, at least one raking device is arranged above each material support platform, and the raking devices above the material support platforms on the same layer of the two fermentation racks are installed on the same traction rope, and the hoisting mechanism can drive the traction rope to reciprocate.
[0017] Furthermore, the raking device includes a raking frame capable of moving along a first relative movement direction above a material support platform, and the angle raking element is a raking knife movably mounted on the raking frame and capable of moving between a raking working position and a non-raking working position. The raking knife extends downward toward the corresponding material support platform at the raking working position and forms an angle with the first relative movement direction.
[0018] Further, the raking device includes a first blade shaft hinged to the raking frame, the raking blade includes a first raking blade installed on the first blade shaft, the first blade shaft is provided with a first stopper, the first relative movement direction includes a positive direction and a reverse direction opposite to each other, when the raking frame moves along the positive direction, the first stopper stops the raking frame to keep the first raking blade downward in the raking working position, and when the raking frame moves along the reverse direction, the first raking blade is lifted up by the material on the material support platform and rotated to the non-raking working position.
[0019] Furthermore, the raking device includes a second blade shaft hinged to the raking frame, the second blade shaft is arranged parallel to and spaced apart from the first blade shaft, the raking knife includes a second raking knife installed on the second blade shaft, and the second blade shaft is provided with a second stopper, when the raking frame moves along the reverse direction, the second stopper stops the raking frame to keep the second raking knife downward in the raking working position, and when the raking frame moves along the positive direction, the second raking knife is lifted up by the material on the material support platform and rotated to the non-raking working position.

[0021] The raking device is made to perform multiple relative movements with the material support platform along the first relative movement direction above the material support platform, so that the angle raking element pushes the material on the material support platform multiple times in a direction forming an angle with the first relative movement direction and finally causes the material to fall from the material support platform.
[0022] Furthermore, the multiple relative movements are multiple reciprocating movements of the raking device above the material support platform along the first relative movement direction, and when the raking device performs forward and backward movements in each reciprocating movement, the angle raking element pushes the material on the material support platform in the same direction.
[0023] Beneficial Effects
[0024] Compared with the prior art, the side-push sewage fermentation treatment system and sewage treatment method of the present invention have the following beneficial effects:
[0025] 1. Since the angle raking element is arranged at an angle with the first relative movement direction at least in the raking working state, when the raking device moves relative to the material support platform along the first relative movement direction above the material support platform, the angle raking element pushes the material on the material support platform along the direction at an angle to the first relative movement direction, that is, a side push is formed on the material relative to the first relative movement direction. In other words, by staggering the traveling direction of the raking device and the raking operation direction of the angle raking element, the traditional raking device for treating waste such as manure is overturned, which adopts the solution that the raking device directly raks and pushes the material along the traveling direction. That is, the traveling direction of the raking device and the raking operation direction are offset at an angle. Each time the raking device moves, it will only cause the material on the material support table to be pushed a short distance along the direction that is angled with the movement direction of the raking device. Only after the raking device moves for multiple times, the material will eventually be pushed out of the material support table in the direction that is angled with the movement direction of the raking device due to multiple short-distance pushing. In this way, the material will not be pushed continuously along the traveling direction as if the raking device directly raked and pushed the material, causing the material to continuously accumulate into blocks, thereby affecting the fermentation and conveying effects of the material. Raking and pushing the material for multiple small distances also greatly prolongs the residence time of the material on the material support table, allowing it to fully ferment.
[0026] 2. In a further solution, the raking device is movably arranged with respect to the material support platform, and is arranged to be able to move at least above the material support platform along the length direction of the material support platform. In this way, the raking device can be made to move along the length direction of the material support platform, and the material finally falls along the width direction of the material support platform. On the one hand, it can make full use of the existing long-plate material support platform, which is suitable for large-scale side-push sewage fermentation treatment systems. On the other hand, because the material finally falls in the width direction of the material support platform instead of falling in the length direction, even if it falls in the width direction of the material support platform with limited size, Because the material is pushed in multiple times and at small distances, it can also achieve a longer waiting time for the material to fall than the traditional method of falling along the length of a very long material support table. In this way, even if the length of the material support table is made very short, the side-push type sewage fermentation treatment system still has sufficient material fermentation time. Unlike the traditional raking device for treating waste such as manure, the raking device directly raks and pushes the material along the direction of travel. It is necessary to extend the length of the material support table as much as possible to increase the material fermentation time. Therefore, the side-push type sewage fermentation treatment system can also be well adapted to small sewage treatment plants or other small outdoor spaces with limited matching space.
[0027] 3. In a further scheme, by setting up two layouts of the first turning rake knife and the second turning rake knife, and by designing one to work in the positive direction while the other does not work, and one to work in the reverse direction while the other does not work, the turning rake device can have the turning rake knife turning and pushing materials during both the forward and return strokes of the reciprocating motion, thereby greatly improving the turning efficiency of the turning rake device during the reciprocating motion.

DETAILED DESCRIPTION
[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.
[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements, or it can be a "transmission connection", that is, a power connection through various appropriate methods such as belt drive, gear drive or sprocket drive. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0046] See also Figures 1 to 13One embodiment of the present invention provides a side-push type waste fermentation treatment system, which includes a fermentation rack 100 and a rake turning device 200. The fermentation rack 100 includes a base frame 101, and multiple layers of material support tables 102 arranged on the base frame 101 from top to bottom. Each layer of the material support table 102 can be provided with a rake turning device 200 that can move along the length direction of the material support table 102. The rake turning device 200 includes an angle rake turning element, which is arranged at an angle with the length direction of the material support table 102. In this way, when the rake turning device 200 moves above the material support table 102 along the length direction of the material support table 102, the angle rake turning element The material on the material support platform 102 (for example, feces to be fermented) is pushed along a direction that is angled with the length direction of the material support platform 102. It can be understood that since the angle turning and raking element pushes the material along a direction that is angled with the length direction of the material support platform 102, after the turning and raking device 200 moves multiple times along the length direction of the material support platform 102, the angle turning and raking element can push the material on the material support platform 102 multiple times along the direction that is angled with the length direction of the material support platform 102, and finally the material on the material support platform 102 can be pushed down to the next material support platform 102 along the width direction of the material support platform 102. In this regard, the core technical concept of the present invention is The angle raking element is arranged at an angle to the moving direction of the raking device 200, so that when the raking device 200 moves above the material support platform 102, the angle raking element pushes the material on the material support platform 102 in a direction that is angled with the moving direction of the raking device 200. That is to say, the core technical concept of the present invention is to stagger the moving direction of the raking device 200 for treating waste such as manure and sewage and the raking operation direction at an angle, which subverts the traditional raking device 200 for treating waste such as manure, which uses the raking device 200 to directly rake and push the material along the moving direction. The advantage of this is that since the moving direction of the raking device 200 The raking device 200 is at an angle to the direction of the raking operation. Each time the raking device 200 moves, it will only push the material on the material support table 102 a short distance in the direction that is angled to the movement direction of the raking device 200. Only after the raking device 200 moves for multiple times, the material will eventually be pushed out of the material support table 102 in the direction that is angled to the movement direction of the raking device 200 due to multiple short-distance pushes. In this way, the material will not be pushed continuously along the travel direction like the raking device 200 directly raking and pushing the material, causing the material to accumulate continuously, thereby affecting the fermentation and transportation effects of the material. The residence time of the material on the material support table 102 is also greatly extended, allowing it to be fully fermented.
[0047] It should be noted that the above is only an embodiment of the present invention and is not intended to limit the present invention. The present invention protects any variation and expansion that meets the following requirements:
[0048] A side-push type waste fermentation treatment system includes a fermentation rack 100 and a rake turning device 200:
[0049] The fermentation rack 100 includes a material support table 102. Regardless of whether the number of the material support tables 102 is 1 or greater than 1, it will fall within the protection scope of the present invention. In the case where the number of the material support tables 102 is greater than 1, whether there are multiple layers arranged in the up and down directions or multiple layers arranged in other directions (for example, multiple layers arranged in the horizontal direction), it will fall within the protection scope of the present invention. However, the above-mentioned embodiment in which the multiple layers of material support tables 102 are arranged on the base frame 101 from top to bottom forms an excellent matching relationship with the special raking device 200 of the present invention, so that the material on the material support table 102 (for example, feces to be fermented) can be raked and dropped layer by layer, which greatly prolongs the residence time of the material on the material support table 102, allowing it to be fully fermented, and the side-push type sewage fermentation treatment system can be arranged along the vertical space as a whole, saving the space arrangement of the side-push type sewage fermentation treatment system in the horizontal direction;
[0050] The raking device 200 is arranged to be in relative motion with the material support platform 102, and the raking device 200 can at least move relative to the material support platform 102 along a first relative motion direction above the material support platform 102. The meaning of "at least" is that the raking device 200 may also be in a fixed state, a state of moving in other directions of the material support platform 102 (for example, below), or a state of moving relative to the material support platform 102 along other relative motion directions (second relative motion direction) above the material support platform 102. The raking device 200 includes an angle raking element, which is arranged at least at an angle with the first relative motion direction in the raking working state (the existence of an angle is considered to be greater than 0° in the present invention), so that the raking device 200 can move relative to the material support platform 102 along the first relative motion direction above the material support platform 102. When the platform 102 moves relative to the material support platform 102, the material on the material support platform 102 is pushed along the direction forming an angle with the first relative movement direction (the existence of the angle is considered to be greater than 0° in the present invention) by the angle raking element. Regardless of whether it is driven by a driving device or manually, as long as the raking device 200 moves relative to the material support platform 102 along the first relative movement direction above the material support platform 102, the angle raking element pushes the material on the material support platform 102 along the direction forming an angle with the first relative movement direction, which will fall within the protection scope of the present invention, which constitutes the core technical concept of the present invention: the travel direction of the raking device 200 and the raking operation direction of the angle raking element are angularly staggered, regardless of whether the first relative movement direction is the length direction or width direction of the material support platform 102 or a direction with a certain degree of deviation from the length direction.
[0051] According to one embodiment of the present invention, the angle raking element is arranged at an angle of 10° to 60° with the first relative movement direction at least in the raking working state, preferably at 45°. Usually, when the angle is around 45°, when the raking device 200 moves above the material support table 102 along the length direction of the material support table 102, the angle raking element pushes the material on the material support table 102 along the direction of the length direction of the material support table 102, that is, the material is pushed perpendicular to the length direction of the material support table 102 (along the width direction of the material support table 102). According to other embodiments of the present invention, the angle raking element, at least in the raking working state, is arranged at an angle less than 10° or greater than 60° with the first relative movement direction, which will fall within the protection scope of the present invention, but the angle should be understood as being greater than 0°.
[0052] According to a preferred embodiment of the present invention, the raking device 200 is movably arranged with respect to the material support table 102, and is arranged to be able to move at least above the material support table 102 along the length direction of the material support table 102. The preferred embodiment clearly stipulates that the raking device 200 is movably arranged, so that the fermentation rack 100 can be fixed, and the raking operation is completed by driving the raking device 200 to move, which is easy to implement and design from a technical principle. However, as mentioned above, the present invention only needs to satisfy the requirement that the raking device 200 and the material support table 102 are arranged in relative motion, that is, the raking device 200 can be stationary while the material support table 102 moves. For example, the raking device 200 itself is absolutely fixed, and the raking effect can be produced by driving the material support table 102 to reciprocate to achieve the above-mentioned relative motion. The raking device 200 can also move while the material support table 102 is stationary. As long as the two can produce relative motion along the first relative motion direction, the scheme will fall within the protection scope of the present invention.
[0053] According to the first embodiment of the present invention, a material drop hole 103 is provided at the edge of the material support platform 102 in the width direction. When the raking device 200 moves above the material support platform 102 along the length direction of the material support platform 102, the angle raking element pushes the material on the material support platform 102 in a direction that is angled with the first relative movement direction and toward the material drop hole 103. The material can fall onto the lower material support platform 102 through the material drop hole 103. According to the second embodiment of the present invention, the material drop hole 103 can be provided in the middle of the material support platform 102 in the width direction. According to the third embodiment of the present invention, even if the material drop hole 103 is not provided on the material support platform 102, it is also acceptable to make the angle raking element push the material to fall directly from the edge of the material support platform 102.
[0054] According to one embodiment of the present invention, the material blanking through hole 103 extends from one end of the material support platform 102 to the other end along the length direction of the material support platform 102 at the edge of the width direction of the material support platform 102. According to another embodiment of the present invention, the material blanking through hole 103 may also be arranged in plurality at the edge of the width direction of the material support platform 102 along the length direction of the material support platform 102 at intervals, rather than in the form of a whole through hole extending from one end to the other end.
[0055] Of course, the above are merely examples of specific implementations of the blanking holes 103, and are not intended to limit the present invention. In fact, any number, shape, and extension direction of blanking holes 103 at any position on the material support table 102 will fall within the protection scope of the present invention.
[0056] According to a preferred embodiment of the present invention, the respective material drop holes 103 of the two adjacent material support platforms 102 are arranged on different sides of the width direction of the material support platform 102, that is, they are staggered. This is to meet the specific setting of the direction of the raking device 200 corresponding to the two adjacent material support platforms 102. In short, the raking device 200 will push the material to move toward the material drop hole 103 during the raking operation, so the respective material drop holes 103 of the two adjacent material support platforms 102 are arranged on the material support platform 10 2 is also possible, so that the running direction of the raking device 200 and the direction of pushing the material can be adjusted accordingly. The running direction of the raking device 200 and the angle setting of the angle raking element are both aimed at making the angle raking elements working on each layer of the material support platform 102 push the material in the direction of the drop hole when the raking device 200 moves, thereby realizing the function of raking and pushing the material layer by layer from top to bottom. Of course, even if the drop hole 103 is not set, it is possible to realize that the material falls directly from the edge of the material support platform 102 layer by layer.
[0057] According to one embodiment of the present invention, at least one raking device 200 is arranged above each material support platform 102, and the side-push sewage fermentation treatment system includes a traction device drivingly connected to the raking device 200, and the traction device is used to pull each raking device 200 to perform reciprocating motion above the corresponding material support platform 102 along the length direction of the corresponding material support platform 102; or, the traction device is used to pull each raking device 200 to perform a circular motion above the corresponding material support platform 102 (it can perform a circular motion in a horizontal plane), and a section of the traveling path of the circular motion is arranged directly above the material support platform 102 along the length direction of the corresponding material support platform 102. According to another embodiment of the present invention, two adjacent material support platforms 102 can share one raking device 200, instead of setting one above each material support platform 102. The raking device 200, a specific example of this embodiment is that each raking device 200 makes a circular motion around the material support platforms 102 of odd or even layers. For example, the 1st, 3rd, 5th, and 7th material support platforms 102 are all equipped with a raking device 200 that makes a circular motion around the material support platforms 102 of that layer. In this way, when the raking device 200 moves under the corresponding material support platform 102, the materials on the 2nd, 4th, 6th, and 8th material support platforms 102 can be raked. According to other embodiments of the present invention, the situation where every 3 layers of material support platforms 102 share one raking device 200, every 4 layers of material support platforms 102 share one raking device 200, and even all material support platforms 102 share one raking device 200 will fall within the protection scope of the present invention. For this purpose, a specific mechanical transmission scheme can be matched, which will not be described in detail here.
[0058] See also Figures 2 to 4According to the first embodiment of the present invention, the number of fermentation racks 100 is 2, and the traction device includes a turning roller 1, a hoisting mechanism, and a traction rope 2 (such as a steel rope, etc.) arranged on the hoisting mechanism and the turning roller 1. Four turning rollers 1 can be arranged on the periphery of two material support platforms corresponding to the same layer of each fermentation rack 100, and the traction rope 2 is wound into a quadrilateral by the four turning rollers 1. The hoisting mechanism can be specifically in the form of a motor 3 driving a reel 4, and the traction rope 2 is wound on the reel 4. At least one turning and raking device 200 is arranged above each material support platform 102, and the turning and raking devices 200 above the material support platforms 102 on the same layer of the two fermentation racks 100 are installed on the same traction rope 2. The hoisting mechanism can drive the traction rope 2 to reciprocate, which can The traction rope 2 is designed to have rope segments arranged along the length direction of the material support platform 102, so that the raking device 200 can be driven to and fro on the material support platform 102 along the length direction of the material support platform 102; according to the second embodiment of the present invention, the hoisting mechanism can drive the traction rope 2 to perform a circular motion; according to the third embodiment of the present invention, the raking device 200 is not driven by such a hoisting mechanism plus the traction rope 2, but can be driven by any one of the gear transmission, belt wheel transmission, and sprocket transmission systems; according to the fourth embodiment of the present invention, the raking device 200 can be driven in mid-air by a micro-aircraft type driving device; according to the fifth embodiment of the present invention, the raking device 200 can be driven by manpower.
[0059] As a specific implementation, see Figure 2 The base frame 101 is provided with a sliding frame 104 extending along the length direction of the corresponding material support platform 102 corresponding to each layer of the material support platform 102, and each rake turning device 200 is slidably installed on the sliding frame 104 corresponding to each layer of the material support platform 102. Specifically, the rake turning device 200 includes a rake turning frame 201 that can move above the material support platform 102 along a first relative motion direction and a guide wheel 202 installed on the rake turning frame 201. The guide wheel 202 is slidably installed in the slide groove of the sliding frame 104. The rake turning frame 201 is also equipped with a rope sleeve 210, and the rope sleeve 210 0 is provided with locking frames 211 at both ends, and locking blocks 212 and locking ratchet 213 are installed on the locking frames 211. The locking ratchet 213 is connected to the locking shaft 214, and the locking shaft 214 is rotatably installed on the locking frame 211. The traction rope 2 passes through the rope sleeve 210 and the locking frame 211, and passes through the locking shaft 214. The traction rope 2 can be locked to the locking frame 211 through the locking ratchet 213 and the locking block 212, so that the traction rope 2 is fixed to the rake frame 201, but the fixing method of the traction rope 2 and the rake frame 201 is not limited to this specific structure.
[0060] See also Fig.11According to one embodiment of the present invention, a material laying auxiliary frame may be provided above the rake frame 201 of the topmost rake device 200. The material laying auxiliary frame specifically includes an outer frame 5 and a plurality of material guide plates 6 arranged at intervals inside the outer frame 5. The outer frame 5 has an upper port and a lower port. The material guide plates 6 are arranged vertically. The material laying auxiliary frame can play a role in evenly laying materials on the top layer. During operation, the material conveying device delivers materials to the upper port of the outer frame 5 through the conveying pipe 7, and the traction rope 2 drives the rake device 200. Then, the material will be driven by its gravity and the thrust of the rake device 200, so that it will fall out from the lower port and fill in the place where the required material laying height is not reached, or fill in the area pushed empty by the angle rake element before, so as to achieve even material laying and well control the feeding and discharging amount of each layer.
[0061] See also Fig.12 According to another embodiment of the present invention, a stirring hopper 8 can be arranged above the rake frame 201 of the topmost rake device 200. The stirring hopper 8 has an upper port and a lower port. A stirring shaft 9 is installed in the stirring hopper 8. A spiral stirring knife 10 is arranged on the outer surface of the stirring shaft 9. The stirring shaft 9 can be connected to a driving device such as a motor. When working, the material conveying device delivers the material into the upper port of the stirring hopper 8 through the conveying pipe 7. After the spiral stirring knife 10 stirs the material, the material falls from the lower port of the stirring hopper 8 to the material support platform 102.
[0062] According to one embodiment of the present invention, the angle raking element is a raking knife movably mounted on the raking frame 201, and is capable of moving between a raking working position and a non-raking working position (which can be achieved through a hinged structure). The raking knife extends downward toward the corresponding material support platform 102 in the raking working position and forms an angle with the first relative movement direction. The angle is the angle between the angle raking element mentioned above and the first relative movement direction at least in the raking working state. A more specific understanding is that, for example, when the first relative movement direction is the length direction of the material support platform 102, the raking knife can extend downward along the first vertical plane in the working position. The vertical plane extending along the length direction of the material support platform 102 is defined as the second vertical plane. The angle between the first vertical plane and the second vertical plane is the raking angle. The angle between the blade and the first relative movement direction, but the turning and raking blade may not strictly extend downward in the vertical direction in the working position, and a slight inclination is also acceptable. In short, the basic design requirement is to be able to turn over and rake the material below it. According to other embodiments of the present invention, the turning and raking blade may be replaced with turning and raking teeth or any other structural form that can realize the turning and raking function, and the turning and raking blade is not limited to being strictly fixed in the working position, but may also be in the form of turning and raking while rotating, or turning and raking while vibrating, or other compound motion forms, but on the premise that the material can be turned over and pushed to the next layer of material support platform 102, the turning and raking blade may be designed to be similar to a plow blade, which can not only realize side pushing of the material, but also turn over the material on the bottom layer, thereby further improving the turning and raking efficiency of the material.
[0063] Regarding further specific implementations of the raking device 200 using the raking frame 201 and the raking blade structure, the present invention provides the following multiple design solutions:
[0064] See also Figures 6 to 10 ,in Figure 6 , Figure 7 , Fig.10 It indicates that the rake frame 201 moves in the positive direction a. Figure 8 and Fig. 9It shows that the rake frame 201 moves in the opposite direction b. According to the first embodiment of the present invention, the rake device 200 includes a first blade shaft 203 hinged to the rake frame 201, and the rake blade includes a first rake blade 204 installed on the first blade shaft 203. The first blade shaft 203 is provided with a first stopper 205 (for example, in the form of a baffle), and the first relative movement direction includes a positive direction a and a reverse direction b opposite to each other. When the rake frame 201 moves in the positive direction a, the first stopper 205 stops at the rake frame 201 to keep the first rake blade 204 downward in the rake working position. The first rake blade 204 can push the material in the direction c. By designing the working position angle of the first rake blade 204 to be at an angle of about 45° with the positive direction a, the direction c is perpendicular to the positive direction a, and the rake frame 201 moves in the reverse direction b. When the rake frame 201 moves in the opposite direction b, the first rake blade 204 is lifted up by the material on the material support platform 102 and rotated to the non-rake working position. The situation in which only the first rake blade 204 is designed can match the situation in which the winch mechanism drives the traction rope 2 to make a circular motion. During the circular motion, each time the rake frame 201 moves to the top of the corresponding material support platform 102, the first rake blade 204 can push the material toward the blanking hole 103 for a short distance. After multiple cycles, the material can be finally pushed out from the blanking hole 103 to the next material support platform 102. When the rake frame 201 moves in the opposite direction b, the first rake blade 204 is lifted up by the material on the material support platform 102 and rotated to the non-rake working position in order to prevent the first rake blade 204 from pushing the material in the direction away from the blanking hole 103 when the rake frame 201 moves in the opposite direction.
[0065] Still see Figures 6 to 10According to the second embodiment of the present invention, the raking device 200 includes a second blade shaft 206 hinged to the raking frame 201, the second blade shaft 206 is arranged parallel to the first blade shaft 203, and the raking knife includes a second raking knife 207 installed on the second blade shaft 206, and the second blade shaft 206 is provided with a second stopper 208 (for example, in the form of a stop rod). When the raking frame 201 moves in the reverse direction b, the second stopper 208 stops at the raking frame 201 to keep the second raking knife 207 downward in the raking working position. When the raking frame 201 moves in the positive direction a, the second raking knife 207 is lifted up by the material on the material support platform 102 and rotated to the non-raking working position. This situation can well match the raking device 200 on the material support platform 102 makes reciprocating motion, when moving forward, the first rake blade 204 works to push the material along the c direction, and when moving backward, the second rake blade 207 works, which can greatly improve the efficiency of rake turning the material. The angle arrangement of the first rake blade 204 and the second rake blade 207 at the working position should be staggered. For example, when the first rake blade 204 is at a 45° angle to the forward motion direction at the working position, the second rake blade 207 is arranged at a 135° angle to the original forward motion direction at the working position. In this way, when the rake frame 201 moves backward, the second rake blade 207 can push the material along the same material pushing direction (for example, c direction) as the first rake blade 204. When there is a multi-layer material support table 102, the material pushing path can be referred to. Fig.13 The materials fall down layer by layer through the action of the rake devices 200 at each layer.
[0066] According to the third embodiment of the present invention, the second raking knife 207 is also installed on the first knife shaft 203 instead of the second knife shaft 206. The first knife shaft 203 is also provided with a second stopper 208. When the raking frame 201 moves in the reverse direction, the second stopper 208 stops the raking frame 201 to keep the second raking knife 207 downward in the raking working position. When the raking frame 201 moves in the positive direction, the second raking knife 207 is lifted up by the material on the material support platform 102 and rotated to the non-raking working position. In this way, the first raking knife 204 and the second raking knife 207 are arranged on the same first knife shaft 203, which can save structure and space layout. The specific working principle can refer to the second embodiment.
[0067] According to a fourth embodiment of the present invention, a raking device 200 includes a first blade shaft 203 hinged to a raking frame 201, and the raking blades include a first raking blade 204 and a second raking blade 207 mounted on the first blade shaft 203, the first raking blade 204 and the second raking blade 207 are arranged at an angle with respect to the axis of the first blade shaft 203, and the first relative motion direction includes a positive direction and a negative direction opposite to each other, when the raking frame 201 moves in the positive direction, the second raking blade 207 stops at the raking frame 201 to keep the first raking blade 204 downward in a raking working position, and when the raking frame 201 moves in the negative direction, the first raking blade 204 stops at the raking frame 201 to keep the second raking blade 207 downward in the raking working position, in this way, the additional first stopper 205 and the second stopper 208 are cancelled, and the positions of the first raking blade 204 and the second raking blade 207 can be reasonably designed so that they have both the raking ability and the ability to stop another raking blade, and the specific working principle can refer to the second embodiment.
[0068] It can be understood that the specific implementation method of the raking device 200 is not limited to the above four embodiments, and the specific structural design can be improved according to special needs, and is not limited to the structure of the raking frame 201 combined with the raking knife. For example, in the above embodiments, when the raking frame 201 switches the raking knife during forward and reverse movement, the corresponding raking knife is pushed up by the material to put it in an inoperative state. However, as other embodiments, a lifting device can be designed for the raking knife, so that the raking knife can descend to work when the raking frame 201 moves forward, and can rise and stop working when the raking frame 201 moves reversely. Similar variations will fall within the protection scope of the present invention. In addition, it can be understood that in order to improve the raking efficiency, in each embodiment, the number of raking knives can be arranged at intervals along the corresponding knife axis.
[0069] According to a preferred embodiment of the present invention, a flange 209 is provided on the first raking blade 204. When the raking frame 201 moves in the positive direction, the flange 209 is located at the front end of the first raking blade 204 in the moving direction. It can be designed to be arranged in the vertical direction or slightly inclined in the vertical direction. During actual operation, after the raking device 200 moves, a wavy line-like material stacking state will be left through the flange 209, and the material is loose, thereby greatly increasing the material evaporation area and the oxygen contact surface. Of course, a similar flange 209 can also be provided on the second raking blade 207 to achieve the same function.
[0070] In addition, the present invention also provides a waste treatment method of a side-push type waste fermentation treatment system, wherein the waste treatment method is carried out using the above-mentioned side-push type waste fermentation treatment system, and the waste treatment method comprises:
[0071] The raking device 200 is made to perform multiple relative movements with the material support platform 102 along a first relative movement direction above the material support platform 102, so that the angle raking element pushes the material on the material support platform 102 multiple times along a direction that is angled with the first relative movement direction and finally causes the material to fall from the material support platform 102. The multiple relative movements can be achieved by circular motion, reciprocating motion or any other form of motion. The first relative movement direction can be the length direction of the material support platform 102. For details, please refer to the specific implementation method of the side-push type sewage fermentation treatment system above. It will not be repeated here, but it can be understood that the sewage treatment method does not rely on the side-push type sewage fermentation treatment system in the specific implementation method of the present invention to be implemented. In short, as long as the two core structures of the material support platform 102 and the raking device 200 exist, regardless of whether there are other structures and devices, and regardless of how the specific structural forms of the material support platform 102 and the raking device 200 are set, as long as the above contents specified by the sewage treatment method are met, they will fall within the protection scope of the present invention.
[0072] The present invention preferably but not limitedly, the multiple relative movements are multiple reciprocating movements of the raking device 200 above the material support platform 102 along the first relative movement direction. When the raking device 200 performs forward movement and backward movement in each reciprocating movement, the angle raking element pushes the material on the material support platform 102 in the same direction. The specific implementation means can refer to the specific implementation method in the above side-push type sewage fermentation treatment system, which will not be repeated here.
[0073] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
